摘要
利用有限元分析软件ABAQUS,对某大型风洞动力段结构进行了有限元分析计算。通过建立动力段网格模型,定义边界条件,得到了风洞动力段结构的应力、应变结果。通过对多种模型的计算和分析,得出影响模型结构强度的关键因素,为动力段结构设计提供了参考依据。计算分析结果表明,本文所建立的动力段模型及算法在适用性及计算时间等方面具有优势,且计算结果也更可靠。
Finite element analysis and simulate on fan stage structure of one wind tunnel use finite ele-ment analysis software ABAQUS. A meshing model of the fan stage is built, deifne the boundary condition, show the stress and displacement results of the fan stage. Simulate and analysis on some models show the key factor which affect the strength of the model, and provide reference for the structure design of the fan stage. Simulate and analysis results show the fan stage model this paper built and the simulate method is much feasible for such problem, the cost of computational time is less than traditional method, and the results is more dependable.
